Cl. 240108 2 Claims ABSTRACT OF THE DISCLOSURE A lampshade is made up of a plurality of identical frames, each frame forming a side of the shade. Each frame has a screen holder for holding a light transmitting panel. The screenholders are adjustably mounted on the frames so that light transmitting panels of different thicknesses may be used. The screen holders fit together edge to edge with projections on one edge projecting into recesses on the opposite edge of the adjacent screen holder.

The following is the specification of this application:

One object of my invention is to create a lampshade construction with lampshade frames which easily can be assembled to form a lampshade.

Another object is to provide a lampshade with interchangeable shade material.

A- further object is to create a lampshade construction which permits the use of shade materials of different thicknesses.

A still further object is to provide a lampshade construction to attach the assembled lampshade in various heights to the lampbase.

Still another object is to create a lampshade for the easy storing and shipping of the different lampshade components.

FIG. 8 shows in a perspective front view a detail of a slot construction of two attached screen supporters.

FIG. 9 shows in a perspective front view a slot securing means. 1

FIG. 10 is a brace socket.

FIG. 11 is the back portion of the same brace socket illustrated in FIG. 10.

FIG. 12 is one form of three lampshade braces.

As shown in the drawings, the lampshade comprises a plurality of frames 1, each frame having an opening 2 to be covered with a shade screen passing light therethrough and a screen supporter 3 surrounding said opening on one side of the frame 1 to press such material against said frame. Said screen supporter 3 is a substantially square shaped frame or may be a rigid transparent plastic plate.

Each frame 1 is provided on its inside portion with a plurality of pin means 4 preferably threaded and each screen-supporter 3 is provided opposite to said pin means 4 with a plurality of pin holes 5.

The pin means 4 of the frames 1 are inserted into the opposite standing pin holes S of the screen supporters 3, to attach said frames and said screen supporters to each other.

A regulating cap 6, preferably threaded, is fastened over the pin means 4 to secure the attached frames 1 and screen supporters 3 to each other, forming thereby four frame units.

The shade screens are placed between the frames 1 and the screen supporters 3 and the proper positioning of said pin means 4 provides said shade screens with vertical and horizontal support. In order to prevent further the vertical and horizontal movement of said shade screens, each shade screen can be provided with a plurality of holes which holes correspond with the number and position of the pin means 4 on the upper and lower portions of the frames 1.

By positioning the shade screens between the frames 1 and screen supporters 3, the pin means 4 of the frames 1 penetrate through the holes of the shade screens and through the pin holes 5 of the screen supporters 3, preventing thereby entirely the movement of the shade screens in any direction.

The extent of the space required for the different thicknesses of the shade screens between the frames 1 and the screen supporters 3, is regulated by the tightening or loosening of the regulating caps 6 over the pin means 4.

To assemble the secured frame units of the frame 1 and screen supporters 3- into a lampshade in a square relationship, each screen supporter 3 is provided with a plurality of spaced attaching means 7 at one end and with a plurality of spaced attaching sockets 8 at the other end. The spaced attaching means 7 at one end of the screen supporters 3 is inserted into the spaced attaching sockets 8 at the other end of the adjacent screen supporter 3 and continued until all the secured frame units are connected with each other.

In order to secure the connected frame units firmly to each other, both vertical ends of each screen supporter 3 are provided with a holding slot 9 and each of the holding slots has a channel portion 10 for a purpose later described.

Four removable slot securing means 11 secure the connected frame units to each other. Each of the slot securing means 11 is provided at both vertical ends thereof longitudinally with a raised holding portion 12.

To secure the connected frame units to each other, the slot securing means 11 is inserted into the holding slots 9 of the adjacent screen supporters 3 and the raised holding portions 12 of the slot securing means 11 by penetrating into the channel portions 10 of the holding slots 9, secure firmly the adjacent and connected frame units to each other.

To release the secured frame units of the frames 1 and screen supporters 3 from each other, the slot securing means 11 should be removed from the adjacent holding slots 9.

To release the secured frames 1 and screen supporters 3 from each other, the regulating caps 6 should be removed from the pin means 4.

In order to prevent the escape of light between the frame units, each frame 1 is provided at one end thereof longitudinally with a light screen 13 and at the other end longitudinally with a light screen supporter 14. By connecting the frame units with each other, the light screen 13 at one end of the frame 1 slides over the other end of the adjacent frame 1 and by penetrating into the light screen supporter 14, covers the joint sections of the connected frame units and gives to the frame units an outside support.

In another form, as shown in the drawings by FIG. 7, the frames 1 and the screen supporters 3 besides the pin means 4 and pin holes 5, are attached to each other at 3 one end also by hinge means 15, for the purpose of faster assembly. Although, hinges in the form of a flexible ma terial have been shown in the drawing, any other hinge mechanism may be employed. All the other parts of the frames 1 and the screen supporters 3 remain unchanged.

In order to attach the assembled lampshade to the lampbase, each screen supporter 3 is provided at one end thereof with a brace socket 16 to receive the end portions of a brace described later. The brace sockets 16 may be formed by the appropriate bending of the center part of the upper horizontal portion of the screen supporter 3. Each of the brace sockets 16 is provided on its outside portion with a brace holding means 17 to provide the inserted brace with a vertical support, and has on its inside portion a horizontal brace supporting means 18, to prevent the horizontal movement of the brace in the brace sockets 16.

A single brace attaches the assembled lampshade to the lampbase. The brace is provided on its center portion with a central means 19 in the form of a hole or a screw cover to attach the lampshade through the central means 19 to the lampbase. Two arms 20 extend from the central means 19 to the two opposite standing brace sockets 16 and the appropriate bending of the arms 20 regulates the height of the lampshade on the lampbase. To insert the arms 20 into the two opposite standing brace sockets 16, each of the arms has an appropriately bent end portion 21 to fit into the brace sockets 16. Each of the end portions 21 has a cut out portion 22, to mate with the horizontal brace support 18 of the brace socket 16, giving thereby a horizontal support to the brace when the end portions 21 are inserted into the brace sockets 16. To attach the brace to the lampshade, the end portions 21 are inserted into the two opposite standing brace sockets 16.

In order to provide the brace with a vertical support, each arm 20 has parallel with the end portions 21 a flexible holding means 23, and the upper part of the holding means 23 ends in a slightly raised portion 24. By inserting the two end portions 21 of the brace into the two opposite standing brace sockets 16, the flexible holding means 23 slides over the outside portion of the brace sockets 16 and the raised portion 24 of the holding means 23 by snapping over the brace holding means 17 on the outside portion of the brace sockets 16, holds said brace in position. Through central means 19, the brace with the lampshade is attached to the lampbase and a screw cap or finial fastens the brace with the lampshade to the lampbase.

All the frames 1 and all the screen supporters 3 are exactly alike and so formed that they may be connected end to end in interchangeable relation.

It is clearly understood that according to the strength of the materials used for the illustrated braces in FIG. 12, they may be narrower or wider in shape and they may be fiat, rectangular or round including the shape of a single wire and the shape of the brace sockets always corresponds with the shape of the end portions of said brace.

It is also understood that said braces can be used not only as a unit with the present invention but also in connection with other lampshades as separate components.

Although but one specific embodiment of the invention has been herein shown and described, it will be understood that said lampshade may be square, round or any other shape and details of the construction shown may be altered or omitted without departing from the spirit of this invention as defined by the following claims.
